High Current Driver /w clicky control

Hi,

I looking for a new high current buck driver (new to me anyway) and hoped you guys might be be able to help out. I'm after either a single driver, or multiple drivers that can be run from a a single piezo (prolongated is ok). Necessary functions are on/off and variable power control (e.g. via PWM, fixed levels would be ok).

I've been using the taskled h6flex which are great, however the 6600ma current limit is less than I need. I also looked at the Ampere! 9A drivers by http://pcb-components.de/, however these seem to have a fault and Tobias has put these on hold for now anyway.

I'd like to run 18 XMLs @ 3000ma using 12v power, so I'm thinking 6 strings of three. If I could parallel two 9A drivers, and control them from a single piezo that would be ideal. Three 6A drivers would also do the job, you get the idea.

If anyone's figured out how to control multiple taskled drivers from a single, please let me know!

Re: High Current Driver /w clicky control

That was in combination with his PWM and Taskled HALLTG and PIEZO ?

you can try with that http://www.ti.com/lit/an/snva431a/snva431a.pdf (I made pcb but not finish it with this chip , but is large because of coil that were recomended ( I go in simulation with lower frequency , bigger components , but with high efficiency )
